如何在python中将列表中的最后一项移到最前面? [英] How do I move the last item in a list to the front in python?

问题描述

我进行了彻底搜索，但没有找到与此确切内容相关的任何内容.我有一个清单:

I searched thoroughly but can't find anything relating to this exact specific. I have a list:

a = [two, three, one]

我想将 one 移到最前面，所以它变成:

I want to move one to the front, so it becomes:

a = [one, two, three]

问题是，列表中可以是任意数量的数字.假设无法知道是否会有50个项目或3个项目.

The thing is, it could be ANY amount of numbers in the list. Assume there is no way of knowing whether there will be 50 items or 3.

推荐答案

基本上:

a.insert(0, a.pop())

考虑使用 collections.deque 不过，如果您经常这样做.

Consider using collections.deque if you're doing that often, though.
